Ingredients

Here’s what you’ll need to make this spinach tofu pasta. You likely have most of this in your kitchen already:

For the Pasta:

• 12 oz (340g) pasta of choice (use gluten-free pasta to keep it GF — fusilli, penne, or rigatoni work great)
• Salted water for boiling
• ½ cup reserved pasta water (set aside before draining)

For the Spinach Tofu Sauce:

• 1 block (14 oz / 400g) silken tofu, drained
• 4 cups fresh spinach (or baby spinach)
• 4 cloves garlic, minced
• ½ medium yellow onion, diced
• 2 tablespoons olive oil
• 3 tablespoons nutritional yeast
• 2 tablespoons fresh lemon juice
• ½ teaspoon salt (adjust to taste)
• ¼ teaspoon black pepper
• ¼ teaspoon red pepper flakes (optional, for a gentle kick)

To Serve (Optional):

• Extra nutritional yeast or vegan parmesan
• Fresh basil leaves
• Cracked black pepper
• Drizzle of good olive oil

How to Make Spinach Tofu Pasta

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Cook your pasta according to package directions until al dente. Before draining, scoop out about ½ cup of the starchy pasta water and set it aside — you’ll use this to adjust the sauce consistency later. Drain the pasta and set aside.

Step 2: Sauté the Aromatics and Spinach

While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the diced onion and a pinch of salt. Cook for about 4 minutes, stirring occasionally, until the onion is soft and translucent. Add the minced garlic and red pepper flakes and cook for another 1–2 minutes until fragrant. Add the fresh spinach in batches and stir until completely wilted, about 2–3 minutes.

Step 3: Blend the Sauce

Transfer the sautéed spinach and onion mixture to a blender. Add the silken tofu, nutritional yeast, lemon juice, salt, and black pepper. Add ¼ cup of the reserved pasta water. Blend on high until completely smooth and creamy. Taste and adjust seasoning — add more lemon for brightness, more nutritional yeast for a cheesier flavor, or more salt as needed. If the sauce seems thick, add another splash of pasta water and blend again.

Step 4: Combine Sauce and Pasta

Pour the blended spinach tofu sauce back into the skillet over medium-low heat. Add the cooked, drained pasta and toss everything together until the pasta is well coated. Let it simmer for 2–3 minutes so the pasta finishes absorbing the sauce. If the sauce has thickened too much, stir in a little more pasta water until you reach a saucy, creamy consistency.

Step 5: Serve and Garnish

Divide into bowls and garnish with fresh basil leaves, a crack of black pepper, a sprinkle of nutritional yeast (or vegan parmesan if you have it), and a small drizzle of olive oil if you’d like. Serve immediately while hot.

Tips for Success

• Use silken tofu, not firm or extra-firm. Silken tofu has a much higher water content, which is exactly what gives this sauce its smooth, pourable consistency. Firm tofu will result in a grainy texture and won’t blend as cleanly.
• Don’t skip the pasta water. That starchy liquid is the secret to getting the sauce to cling perfectly to the pasta. It also helps thin the sauce gradually without watering down the flavor.
• Sauté, don’t skip. Cooking the onion and garlic before blending them into the sauce adds a layer of depth and sweetness that raw aromatics just can’t provide.
• Fresh lemon makes a difference. Bottled lemon juice works in a pinch, but fresh lemon juice is brighter and more vibrant here — and the sauce is already minimal on ingredients, so every one counts.
• Taste as you go. Once the sauce is blended, give it a real taste. Nutritional yeast, lemon, and salt are easy to add and can totally transform the flavor from good to great.
• Baby spinach works perfectly. If you only have baby spinach on hand, go for it — it wilts faster and has a slightly milder flavor.
• Frozen spinach is a great shortcut. If using frozen spinach, thaw it completely and squeeze out all the excess liquid before cooking. Too much water will dilute your sauce.

Storage Instructions

• Refrigerator: Store leftover spinach tofu pasta in an airtight container in the fridge for up to 4 days. The sauce may thicken as it cools — just add a splash of water or vegetable broth when reheating and stir well.
• Freezer: The sauce (on its own, without pasta) freezes beautifully. Pour it into a freezer-safe container or silicone ice cube tray and freeze for up to 2 months. Thaw overnight in the fridge and blend again for best texture before using.
• Reheating: Reheat on the stovetop over medium-low heat with a splash of water, stirring frequently. You can also microwave in 60-second intervals, stirring between each. Avoid high heat, which can break the texture of the sauce.
• Make it ahead: The sauce can be made 3–4 days in advance and stored in the fridge separately from the pasta. Toss with freshly cooked pasta when you’re ready to eat for the best texture.

Variations

• Add roasted vegetables. Toss in some air-fried or roasted mushrooms, cherry tomatoes, zucchini, or broccoli florets. The sauce pairs beautifully with almost any vegetable.
• Make it higher protein. Stir in a can of drained white beans or chickpeas right before serving for extra bulk and protein.
• Spice it up. A teaspoon of white miso paste blended into the sauce adds incredible umami depth. A spoonful of Dijon mustard works similarly.
• Sun-dried tomatoes. Stir in a handful of chopped sun-dried tomatoes for a sweet, tangy contrast to the green sauce.
• Make it a cold pasta salad. Let everything cool completely and toss with cherry tomatoes, arugula, and a squeeze of lemon for a vibrant pasta salad that’s great for meal prep.
• Swap the pasta. This sauce works on zucchini noodles, spaghetti squash, rice noodles, or lentil pasta for an extra protein boost.
• Basil-forward version. Add ½ cup fresh basil leaves directly into the blender with the other sauce ingredients for a pesto-like twist.
